NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
837 am CST Sat Nov 22 2014 


Update... 
quick update to the zones mainly to eliminate the higher probability of precipitation 
that bled over into the late afternoon period from the evening 
period. Have reduced probability of precipitation generally to the 20 to 30 percent 
range for this afternoon over land areas...and frankly even that 
might be generous based on latest guidance. Also made some minor 
adjustments to hourly temperatures to capture latest observation 
trends. 


Otherwise...forecast looks to be on track and no additional 
updates are anticipated before this afternoon/S package. 


&& 


Previous discussion... /issued 458 am CST Sat Nov 22 2014/ 


Discussion... 
the main concern during the forecast period is the potential for 
severe weather late tonight into Sunday morning across the entire 
forecast area. There have been a few changes made to the forecast 
in regards to timing and the outlook by the Storm Prediction 
Center. The storm prediction upgraded the severe weather outlook 
to an enhanced threat over our area for late Saturday night into 
the early morning hours Sunday. The latest guidance still shows 
the slowing trend in the forecast and does not really get 
widespread precipitation until after midnight tonight with the 
highest chance of severe weather being between midnight Saturday 
night though at least the middle morning hours on Sunday. Have 
adjusted probability of precipitation to reflect the new timing and threat to the forecast 
area. 


Digging into some of the parameters and soundings there are a few 
alarming things that show up in the data. Moisture will not be a 
problem as precipitable water values will be approaching 2 inches 
Saturday night and Sunday morning. The kinematics and lift will be 
plentiful as shear and diffluence aloft will be able to support 
severe thunderstorms. The few things that are alarming come to 
light as you look at the model soundings. The GFS is more ominous 
than the NAM. The gfsbufr soundings show very high 0-3km helicity 
values approaching the 400 m2/s2 by 9z Sunday morning with cape 
values of 1600 j/kg at kmsy. The same values are also depicted at 
kasd...and also for kgpt by 12z. If these values were to verify 
there could be some dangerous storms ongoing in the wee hours of 
Sunday morning. The NAM is slower and not as strong and does not 
paint the same picture. The NAM parameters keep the highest values 
out over the Gulf and the European model (ecmwf) seems to be somewhere in the 
middle of both solutions. Of course we will have to see what 
happens today and see how well the atmosphere recovers and the 
track of the surface low and trough will greatly have a influence 
on the severity and placement of the strongest storms and squall 
line. The same limiting factors that were discussed in the 
previous forecast exist. The main one that I see that could 
happening is any convection out over the coastal waters could 
limit the inflow and dampen the atmosphere over the land. So this 
will definitely have to be watched throughout the day and into the 
evening to see how this evolves. 


We are still expecting the main Mode of severe weather to come in 
the form of a squall line tonight with damaging straight line 
winds. With the atmospheric conditions that could be in place over 
the area any storms that form ahead of the line will have the 
greatest chance for producing tornadoes. There also is a heavy 
rain threat with this system. We are still thinking that 2 to 3 
inches of rain could fall over the entire event and with the area 
being fairly dry we are not anticipating widespread flash flooding 
problems. However with the amount of moisture in the atmosphere 
and high rainfall rates possible east could see some nuisance 
type street flooding or pounding of water in low lying and poor 
drainage areas. Have decided not to issue a Flash Flood Watch but 
will let the day shift have the final decision with that. 


Last hazard to talk about with this event is the coastal flood 
threat. Persistent moderate to strong onshore flow has already 
resulted in tidal rises on east facing shores. This trend should 
continue through tonight and some minor/nuisance coastal flooding 
will be possible outside of levee protection for areas from Bay 
Saint Louis to the mouth of the Mississippi River. A coastal Flood 
Advisory is in effect for these areas from noon today through 6 am 
Sunday. 


Conditions should improve rapidly from west to east by middle to late 
morning across the area and no changes were really made after 
Monday with the current forecast. The cold front finally swings 
through the area Sunday night bringing cooler and drier air with 
it. A reinforcing front is forecast to move through the area 
Tuesday night...but with very little moisture in place...expect it 
to come through dry. 


With all of that being said...the main take away should be please 
stay abreast of the weather situation for later on this evening 
and overnight hours. The greatest window for severe weather will 
be after midnight tonight through Sunday morning. Check our social 
media pages and our main website for the latest today in regards 
to the severe weather threat tonight. 


Marine... 
windy conditions over all of the waters. A deepening surface 
low will move from eastern Texas through the arklamiss and into western 
Tennessee. This will keep the winds strong through sun with onshore 
flow. The persistent strong onshore flow will also lead to higher 
than normal tides beginning later today. Numerous showers and 
thunderstorms will also impact the marine zones late today and 
through Sun morning until a squall line moves through. A cold front 
will finally move through late Monday but as this happens winds will 
get another surge back into scy criteria. Moderate to strong 
offshore will remain over the region Tuesday through much of next week. 


Aviation... 
tafs will remain quiet through at least the first half 
of the day and possibly through 0z. By that time though convection 
will begin to roll into the region and tafs will begin to head 
downhill through the night.
